I used a stepping motor to dial the lock, an optical sensor to check rotational place, an enormous solenoid to yank the hasp, and one other optical sensor to detect when the hasp opened. I additionally initially had rotational positioning issues till I adjusted the stepper current and motor start, ramp and prime velocity, and even then added the rotational sensor to detect for and then appropriate any driftage. My outdated Tandy 286 operating Mark Williams C ran the factor via the parallel port. Sure, it wasn't actually practical, particularly as you should buy a kind of locks for only a few dollars, however it was enjoyable to make, and debug, and was a terrific thrill when it successfully opened a lock that I' d forgotten the mixture of. 64,000? I don't know whether or not repeated values are allowed in those simple Master locks. At one number per second, that's lower than a day even if every quantity needs to be tried. 8000, or about 2 hours at one strive per second. I have an outdated Mosler safe having four numbers with values from 0-99; that would take longer - 100,000,000 possibilities? I do know that repeated values are allowed within the Mosler because the combination is consumer-setteable. So, maybe 3 years at one try per second?
